为了便于理解，本申请以下实施例将以具有图1和图2所示结构的电子设备为例，结合附图和应用场景，对本申请实施例提供的基于通讯录的设备发现方法进行具体阐述。
随着通信技术和服务的不断发展，电子设备的形态越来越多。按照电子设备的形态和使用场景，可以将电子设备区分为个人设备和家庭设备，例如手机和手表属于个人设备，而音箱，电视，平板，摄像头等属于家庭共享设备。
应理解，个人设备，一般是移动设备，例如可以是用户可以随身携带的电子设备；家庭设备，一般是固定设备，一般适用于比较紧密的用户关系间拨打，有比较高的隐私要求。
还应理解，目前的个人设备和家庭设备都可以实现拨打电话的功能，例如用户可以通过手表接听或者拨打电话，在使用个人设备接听或者拨打电话的过程中，用户不关心拨打的人使用的是手机1，还是手机2，或者手表3，只要能使用户拨通电话就可以了，提供通用的呼叫服务，还可以设置在接收到呼叫时，手机和手表同时振动。
在和家人的亲情通话过程中，用户可以通过家庭设备进行接听电话或者视频通话。对于用户通过家庭设备拨打电话时，有明确的接听预期，例如拨打的是妈妈家的电视，大伯客厅的音箱等，需要提供妈妈家的电视设备、大伯客厅的音箱设备的单独发现和拨打能力。
对于不同的设备形态或者用户的使用场景，在通话服务过程中需要满足不同的用户需求。图3是本申请实施例提供的一例基于通讯录的音视频通信方法的图形用户界面(graphical user interface，GUI)的示意图，本申请将以手机作为电子设备，详细介绍本申请提供的在基于通讯录的设备发现方法。其中，图3中的(a)图示出了手机的解锁模式下，手机的屏幕显示系统显示了当前输出的界面内容301，该界面内容301为手机的主界面。该界面内容301显示了多款第三方应用程序(application，App)，例如通讯录、信息和联系人等。应理解，界面内容301还可以包括其他更多的应用程序，本申请对此不作限定。
在现有的通话服务中，用户可以基于通讯录对联系人进行呼叫。如图3中的(a)图所示，用户点击“联系人”应用图标，响应于用户的点击操作，手机进入如图3中的(b)图所示的通讯录界面302。在该通讯录界面302上，可以包括联系人列表，用户点击“妈妈” 对应的列表栏，手机显示如图3中的(c)图所示的界面303，该界面303包括联系人“妈妈”的通讯录信息，例如(c)图所示的电话号码和头像等，该界面303还包括快捷菜单列表，例如视频通话、发送信息、共享联系人、添加到个人收藏、共享我的位置等不同的菜单选项，用户可以根据使用需求点击不同的菜单，以实现不同的功能。
例如，用户可以执行如图3中的(c)图所示的点击示出的“视频通话图标10”的操作，响应于用户的点击操作，手机对妈妈发起视频通话请求。以上列举了一种用户发起视频通话的过程，该过程仅仅通过手机通讯录实现对另一用户的通话请求或者视频通话请求，不能实现在多个不同的设备之间发起通话请求或者视频通话请求。
应理解，用户可以通过点击图3中的(c)图所示的任一个“视频通话图标10”都可以向妈妈用户发起视频通话请求，本申请对此不作限定。
此外，除了依赖于运营商发起对另一用户的通话请求或者视频通话请求之外，目前部分方案也支持在手机通讯录中呈现facetime服务，用户通过在手机、PAD等关联设备上设置相同的手机号码、电子邮件等账户，从而可以通过一个设备拨打到用户的手机、手表、PAD等关联设备上，且可以使得多个关联设备同振。
应理解，本申请中，同振可以理解为所述关联设备同时振动，例如有电话呼入时，用户的手机和手表同时发生振动，提醒用户当前的电话呼入，并且当用户通过关联设备中的任一个设备接通电话后，停止对其他关联设备的呼叫。
还应理解，同振状态不限于通过振动的方式提醒用户，还将可以通过铃声、或者铃声且振动的方式提醒用户，本申请对此不作限定。
由上可知，现有的方案仅提供了移动设备的呼叫服务，在拨打到个人设备时，关联设备可以同振，但是该方案没有扩展到家庭设备，如音箱、电视等家庭共享设备；同时缺乏生态扩展性，无法支持未来更多的新兴设备，例如车载设备、无人机等设备。
因此，本申请将提出一种基于通讯录的设备发现方法，能够基于通讯录发现用户的个人设备和家庭设备，并可以将移动设备的呼叫服务扩展到家庭设备，提高用户体验。
图4是本申请实施例提供的一例基于通讯录的音视频通信方法的用户界面示意图。如图4所示，(a)图示出了手机的解锁模式下，手机的屏幕显示系统显示了当前输出的手机的主界面401。该主界面401可以包括多款App，本申请对此不作限定。
如图4中的(a)图所示，用户点击“联系人”应用图标，响应于用户的点击操作，手机进入如图4中的(b)图所示的通讯录界面402。通过本申请提供的方法，在该通讯录界面402上，在下方的菜单栏，除了电话、联系人、个人收藏的菜单之外，本申请可以为用户提供“畅连通话”菜单，如图(b)中示出的畅连通话图标20。
可选地，当该畅连通话图标20存在于通讯录界面402的下方菜单栏时，用户通过点击该畅连通话图标20，手机的通讯录界面402可以仅显示支持畅连通话功能的联系人列表。
可选地，该畅连通话图标20还可以存在与联系人列表中，例如可拨打的联系人中，“妈妈”选项后包括的畅连通话图标20。用户点击“妈妈”选项后包括的畅连通话图标20，可以直接快捷启动畅连通话功能，向妈妈发起视频通话请求。
应理解，本申请提供的“畅连通话”功能用于实现多种设备之间的音视频通信，例如，启动畅连通话功能，用户可以在个人设备和家庭设备之间的音视频通信。
还应理解，本申请的音视频通信服务是自建的IP服务，不同于运营商的电话。
还应理解，在本申请中，如图4中的(c)图所示，图标30用于表示该设备支持接听和拨打电话，图标40用于表示可以该设备支持音频通话，图标20用于表示该设备支持视频通话，本申请对图标的形状、数量和排布顺序不做限定。
在手机的通讯录界面402上，还可以包括机主用户的信息，例如图4中的(b)图示出的“Me”。用户点击“Me”选项，手机显示如图4中的(c)图所示的机主用户的详情界面403。在该界面403上，可以显示多个不同形态的机主用户的可拨打的设备。示例性的，当前手机为华为P30，可拨打的设备可以包括手机华为MATE 20X、平板、智慧屏、手表、音箱等。当用户执行如图4中的(c)图所示的点击“我的手表”选项的拨号图标，响应于用户的点击操作，手机进入如图4中的(d)图所示的呼叫界面404。相应地，在被呼叫的手表端，可以呈现如图4中的(e)图所示的被呼叫界面405。
应理解，对于界面403上显示的机主用户可拨打的设备列表中的每一项设备，可以进行添加。在一种可能的实现方式中，用户可以在手机上编辑添加相应的设备信息，类似于用户手动增加联系人的操作，例如，在“Me”的选项中添加平板、智慧屏、手表、音箱等设备的信息，此处不再赘述。
在另一种可能的实现方式中，可以通过不同设备的专属APP导入到“Me”的选项中。例如，多个不同的设备可以通过同一手机号码进行注册，即平板、智慧屏、手表、音箱等设备都对应于“Me”用户的手机号码，则手机可以自动发现同一手机号码对应的平板、智慧屏、手表、音箱等设备信息，并自动添加到可拨打设备的列表中。
或者，当多个不同的设备对应一个生产厂商时，例如平板、智慧屏、手表、音箱都是华为产品，用户都用一个华为企业账号进行登录，则手机可以自动发现同一华为企业账号对应的平板、智慧屏、手表、音箱等设备信息，并自动添加到可拨打设备的列表中，本申请对可拨打设备的列表中包含的设备数量、添加设备的方式不做限定。
根据图4介绍的方法，可以发现一个账号的多个不同设备，例如个人设备和家庭设备等，可以在一个账号关联的多个不同设备之间进行音视频通信，可以在不同场景下满足用户音视频通信的需求。例如，当用户希望跟家人进行视频通话时，可以将家里的电视和用户手机关联为一个账号下的设备，用户可以在可拨打的设备列表中选择电视，点击视频通话，就可以向家里的电视发出视频通话请求，从而和家人通过电视进行视频通话。或者，当用户在家里找不到手表时，可以向手表发出拨号服务，手表会通过振动或者响铃的方式对用户进行来电提醒，方便用户找到手表，此处不再赘述。
应理解，本申请中，一个账号可以是通过一个手机号码注册的账号，或者设备厂商的企业账号，本申请对此不做限定。
图5是本申请实施例提供的又一例基于通讯录的音视频通信方法的用户界面示意图。如图5所示，(a)图示出了手机的解锁模式下，手机的屏幕显示系统显示了当前输出的手机的主界面501。该主界面501可以包括多款App，本申请对此不作限定。
如图5中的(a)图所示，用户点击“联系人”应用图标，响应于用户的点击操作，手机进入如图5中的(b)图所示的通讯录界面502。如图5中的(b)图所示，用户点击界面502下方的联系人菜单，手机显示如图5中的(c)图所示的所有联系人的界面503。
在该界面503上，包括多个联系人的信息。多个联系人中包括可以进行畅连通话的联 系人和不可以进行畅连通话的联系人，其中可以进行畅连通话的联系人的列表中可以显示畅连通话图标20，联系人的列表中不显示畅连通话图标20的是不可以进行畅连通话的联系人。示例性的，妈妈和娜娜的列表中包括畅连通话图标20，则妈妈和娜娜是可以进行畅连通话的联系人。
应理解，本申请中可以进行畅连通话的联系人，可以是该联系人注册或者接收的畅连通话服务的用户。可选地，当用户B首次点击图5中的(b)图的右下方菜单的畅连通话图标20时，用户授权启动畅连通话功能，或者用户在该畅连通话功能中进行了注册，该畅连通话对应的云端或者服务器就可以获取该用户B的信息，例如注册的手机号码信息或者用户名、账号信息等，从而在用户A的通讯录列表中就可以显示该用户B是可以进行畅连通话的联系人，本申请对此不做限定。
如图5中的(c)图所示，用户点击妈妈的列表栏，手机显示如图5中的(d)图所示的界面504，该界面504包括联系人“妈妈”的通讯录信息。其中，界面504中可以包括畅连通话菜单，当用户点击该畅连通话菜单，手机显示如图5中的(e)图所示的界面505。在该界面505上，包括妈妈关联的多个不同设备，例如，妈妈的平板、音箱、电视、电视2等，其中平板、电视、电视2可以支持视频通话，音箱可以支持音频通话。如果此时用户希望通过电视和妈妈进行视频通话，图5中的(e)图所示，用户点击电视选项的畅连通话图标20，即可向妈妈的电视发起视频通话请求。
在一种可能的实现方式中，当用户通过手机A向平板、手机B、手表等个人设备发起通话请求时，可以将手机A与平板、手机B、手表等个人设备设置为同振状态。从而，当用户通过手机A向平板、手机B、手表等个人设备中的任意一个设备发起通话请求时，平板、手机B、手表等个人设备中的所有设备都会振动，以提醒用户可以通过其中任意一个个人设备接听通话。
在另一种可能的实现方式中，当用户通过手机A向音箱、电视等家庭设备发起通话请求时，可以将手机A与音箱、电视等家庭设备设置为不同振状态。从而，当用户通过手机A向音箱、电视等家庭设备中的任意一个设备发起通话请求时，仅用户选择通话的设备会振动，以提醒用户接听通话，而其他的家庭设备不会振动。
应理解，鉴于家庭设备具有更严格的隐私策略，因此可以将家庭设备设置为非同振状态。还应理解，用户也可以根据个人使用需求，将平板、手机B、手表等个人设备设置为非同振状态，将音箱、电视等家庭设备设置为同振状态，本申请对此不做限定。
应理解，本申请中，同振可以理解为所述关联设备同时振动，例如有电话呼入时，用户的手机和手表同时发生振动，提醒用户当前的电话呼入，并且当用户通过关联设备中的任一个设备接通电话后，停止对其他关联设备的呼叫。
还应理解，同振状态不限于通过振动的方式提醒用户，还将可以通过铃声、或者铃声且振动的方式提醒用户，本申请对此不作限定。
还应理解，除了设置为同振之外，还可以包括顺振。所谓顺振，是指呼叫过程中首先呼叫多个关联设备中的第一个，当该第一个设备在预定时间内没有应答时，按照预定的顺序呼叫该多个关联设备中的第二个，以此类推，并且通常当用户通过关联设备中的任一个设备接通电话后，则不再对后续的其他关联设备进行呼叫，本申请对此不做限定。
根据图5介绍的方法，手机可以基于通讯录发现不同账号的不同设备。例如在用户A 的手机上保存有用户B的通讯录，用户A的手机可以发现用户B支持畅连通话的个人设备。或者，当用户B公开家庭设备信息后，用户A的手机也可以发现用户B支持畅连通话的家庭设备。从而用户A可以对用户B的多个不同设备发起音视频通信请求，可以在不同场景下满足用户音视频通信的需求。
可选地，用户B可以设置是否公开自身关联的多个设备的信息。
例如，用户B设置公开自身关联的多个设备的信息，则用户A的手机就可以发现用户B关联的多个设备，对于用户A的手机，可以显示图4中的(b)图所示的“发现新开启的联系人”，并将用户B关联的多个设备添加到图4中的(c)图所示的可拨打的设备列表的界面。
或者，用户B设置公开自身关联的部分设备的信息，例如仅公开用户B的个人设备的信息，对于用户A的手机，仅可以发现用户B的个人设备的信息，并将用户B关联的个人设备添加到图4中的(c)图所示的可拨打的设备列表的界面。
又或者，用户B设置公开用户B的部分家庭设备的信息，例如仅公开用户B关联的音箱的信息。对于用户A的手机，仅可以发现用户B的音箱设备的信息，并将用户B关联的音箱设备添加到图4中的(c)图所示的可拨打的设备列表的界面，本申请对此不做限定。
应理解，以上的不同实现方式可以通过每个设备的独有App进行控制。例如，当与智慧屏设备，用户B初始登录时，需要通过该智慧屏独有的App注册或登录，用户B还可以为该智慧屏建立设备通讯录，该设备通讯录仅针对与用户B的智慧屏设备，只有当用户授权将智慧屏的设备通讯录导入用户B的手机时，用户B才可以从手机查看用户B的智慧屏的通讯录，并确定该通讯录中是否有用户B的音箱、平板等其他设备信息。
此外，以上的智慧屏时针对私人用户，用户B可以在自己的平板、手机、音箱等多个电子设备中共享设备通讯录。当对于企业的智慧屏设备，大部分购买智慧屏用来进行视频会议，则可以在智慧屏对应的独有控制App内部设置该智慧屏通讯录为所有人可见状态，或者指定通讯录可见，又或者所有人不可见，本申请对此不做限定。
通过以上方法，用户可以针对不同的使用需求，设置权限，从而在被其他设备发现时满足不同场景下不同设备使用过程的隐私要求。
综上所述，以用户A的手机为中心，该手机可以在通讯录中可发现呼叫服务和个人设备、家庭设备等，不仅可以给本人(用户A)的各个设备拨打电话，也可以给某个其他联系人(用户B)或其家庭设备拨打电话。该方法不仅沿用了用户基于通讯录的通话习惯，而且也为万物互联的5G时代提供了易于使用、易于扩展的设备接入能力，提高了用户体验。
此外，上述个人设备、家庭设备在注册过程中，可以使用相同的账号，例如绑定相同的手机号或者使用同一个企业账号，从而可以发现支持呼叫服务的个人设备和家庭设备，并在手机通讯录中呈现呼叫服务、个人设备和家庭设备的列表，用户操作简单，易于演进，提高了用户体验。
结合上述实施例及相关附图，本申请实施例提供了一种基于通讯录的设备发现方法以及音视频通信方法，该方法可以在如图1、图2所示的具有触摸屏和摄像头的电子设备(例如手机、平板电脑等)中实现。

表1
Figure PCTCN2020113714-appb-000001
上述方案，首先将用户的一个或者多个的个人设备使用手机号码在通信账号系统进行注册，开通用户的通信能力。如果需要在一个通讯录条目下设备发现，则第二用户的多个设备可以使用同一个手机号码进行注册。注册完成后，通信账号系统负责维护设备和手机号的绑定关系，可用于能力发现和查询。
图7是本申请实施例提供的一例音视频通信方法的示意性交互图，如图7所示，该方 法可以包括以下步骤：
701，第一用户向通信账号系统进行账号注册。可选地，第一账号可以通过第一用户的第一手机号码进行注册。
702，第二用户向通信账号系统进行账号注册。同理，第二用户可以通过第二用户的第二手机号码进行注册。
应理解，当第一用户通过第一手机号码进行注册，第二用户通过第二手机号码进行注册之后，即第一用户、第二用户都开启了音视频通信能力。
703，第二用户的手表通过第二用户的第二手机号码向通信账号系统进行账号注册。
704，第二用户的电视通过第二用户的第二手机号码向通信账号系统进行账号注册。
705，第二用户的音箱通过第二用户的第二手机号码向通信账号系统进行账号注册。
706，第一用户打开通讯录，和第二用户进行通信。
707，第一用户基于第一用户的通讯录中第二用户的第二手机号码，查询第二用户的设备列表和通信信息。
示例性的，如图5中的(e)图所示，妈妈作为第二用户，第二手机号码保存在第一用户的通讯录中。可以通过查询第一用户的通讯录中的第二用户的信息，确定第二用户的设备列表。例如，(e)图中可以在妈妈的信息中，查询到妈妈的平板、音箱、电视、电视2都可以支持畅连通话，第一用户可以与其中任意一个设备进行音视频通信。
708，第一用户向第二用户的个人设备发起呼叫请求，首先第一用户向音视频通信系统发送呼叫第二用户的个人设备的请求。

或者，713，第一用户向第二用户的音箱发起呼叫请求，首先第一用户向音视频通信系统发送呼叫第二用户的音箱的请求。
714，再由音视频通信系统向第二用户的音箱发起呼叫请求。
上述方案，首先将用户的一个或者多个的个人设备使用手机号码在通信账号系统进行注册，开通用户的通信能力。如果需要在一个通讯录条目下设备发现，则用户的多个设备可以使用同一个手机号码进行注册。在设备通过手机号码注册到通信账号系统的过程中，安全认证可以通过短信验证码保证，也可以通过第三方企业(例如运营商等)提供的免密一键登陆，提高了注册过程的安全性。注册完成后，通信账号系统负责维护设备和手机号的绑定关系，可用于能力发现和查询。
在第一用户向第二用户的设备拨打音视频通信过程中，需要先根据第二用户的第二手机号码查询到满足隐私策略的设备列表，并在通讯录中展现可拨打音视频通信的设备列表。而后第一用户可通过呼叫服务拨打到第二用户的个人设备，个人设备可以实现同振，第一用户也可以直接单点拨打第二用户的音箱、电视等家庭设备。
对于高隐私场景下的家庭设备，如电视、音箱等，要实现可以在第一用户的通讯录中被发现和被呼叫，需要制定明确的隐私策略，例如电视有自己的设备通讯录，只有第一用户在电视自己的设备通讯录中，在第一用户的通讯录中才可以发现该电视和向该电视发起音视频呼叫请求。
通过上述方案，可以基于通信录提供呼叫服务，既可以实现拨打同一用户的不同设备，还将呼叫服务扩展到高隐私场景下的家庭设备、车载设备乃至更多5G通信设备，实现一键发现、拨打和呼叫服务，针对不同的使用场景，提供易用的通信方案，提高了用户体验。
在另一种可能的实现方式中，当第一用户和第二用户向通信账号系统进行注册时，可以通过手机号码进行注册，也可以通过其他的账号、用户名等方式进行注册。这里不论是第一手机号码或者其他的账号、用户名等方式都可以用于唯一确定第一用户或者第二用户即可，本申请对此不做限定。
例如，如果第三方企业(例如手机厂商等)或者服务商已经存在了很完善的账号系统，音视频通信能力只是新增的服务，可以和现有的账号系统融合。具体地，在设备进行注册前，登陆第三方账号系统，获取针对不同用户的符号或者标识(token)；随后，设备再到通信账号系统上进行注册，并完成云侧不同用户的标识鉴权，即满足OAuth2.0的鉴权标准。
在本实施例中，第一用户、第二用户、第一用户的设备、第二用户的设备都在第三方账号系统有相应的注册，且在第三方账号系统中，对于不同的用户，具有不同的用户标识。
图8是本申请实施例提供的又一例音视频通信方法的示意性交互图，如图8所示，该方法可以包括以下步骤：
801，第一用户登录第三方账号系统，获取第一用户标识。
802，第一用户使用第一手机号码向通信账号系统进行账号注册，且携带第一用户标识。
803，通信账号系统对第三方账号系统进行用户鉴权，确认第一用户标识。
804，第二用户的手机通过第二用户的第二手机号码向通信账号系统进行账号注册。
805，第二用户的手表通过第二用户的第二手机号码向通信账号系统进行账号注册。
806，第二用户的电视通过第二用户的第二手机号码向通信账号系统进行账号注册。
807，第二用户的音箱通过第二用户的第二手机号码向通信账号系统进行账号注册。
应理解，通过以上步骤，将第三方账号系统中的注册和用户通过手机号码在通信账号系统的注册进行统一，如果第三方账号已经使用手机号注册，音视频通信能力也可以直接获取此手机号完成端云校验，可以节省用户输入手机号、短信验证等流程，方便用户操作，提高了用户体验。
此外，步骤808-816为设备发现和呼叫过程，与实例一的步骤706-714相同，请参考上述描述，此处不再赘述。
上述方案，首先将用户在第三方账号系统中的注册和用户通过手机号码在通信账号系统的注册进行统一，从而开通用户的通信能力。将同一个用户的多个设备使用同一个手机号码进行注册，可以在一个通讯录条目下被设备发现，可用于能力发现和查询。

对于高隐私场景下的家庭设备，如电视、音箱等，要实现可以在第一用户的通讯录中被发现和被呼叫，需要制定明确的隐私策略，例如电视有自己的设备通讯录，只有第一用户在电视自己的设备通讯录中，在第一用户的通讯录中才可以发现该电视和向该电视发起音视频呼叫请求。
通过上述方案，可以基于通信录提供呼叫服务。既可以实现拨打同一用户的不同设备，还将呼叫服务扩展到高隐私场景下的家庭设备、车载设备乃至更多5G通信设备，实现一键发现、拨打和呼叫服务，针对不同的使用场景，提供易用的通信方案，提高了用户体验。
